Common pitfalls to watch for during CMJ assessments
Ensure the subject minimizes excess movement before the jump, as it affects the initial hip height measurement
Avoid following the jump upward with the camera, as this changes where the initial hip height is measured
Do not adjust the subject's position while already recording, as repositioning affects their positioning in the assessment
Start recording before the subject sinks into their counter movement, not after they've already begun the downward motion
